Raw pictures need pixel layout, row stride and timing context
Raw frame bytes do not automatically describe their width, pixel format, row layout or timing. Row padding is not extra picture detail. A receiver needs the actual representation supplied by the producer, and a renamed raw file is not a self-describing movie container with recovered audio or frame-rate information.

Obtain the producer’s format description first
Record the intended frame dimensions, pixel representation, row stride and sequence timing from the actual producing workflow. A packed RGB24 example uses three bytes per pixel before any row padding, but that calculation is not a rule for every planar, packed or higher-bit-depth format.
If the producer stores padded rows, distinguish meaningful pixels from alignment bytes. Do not infer the image width merely from total file size when multiple interpretations are possible. A plausible-looking partial picture can result from a wrong interpretation and still distort colors, geometry or frame boundaries.
Configure a suitable local receiver for the known layout
Use an import workflow that supports the actual raw representation and its stride arrangement. When using a local FFmpeg rawvideo input, consult its documented pixel-format, size and frame-rate controls rather than assuming those values were embedded in a container header. If the supplied row layout is unsupported, obtain an appropriate documented conversion from the producing workflow.
The website’s upload utilities do not advertise arbitrary headerless raw-frame interpretation or recovery of unknown capture settings. Use supported self-contained media for those tools. Do not paste a guessed extension onto raw bytes and claim that the operation generated the missing metadata or soundtrack.
Verify geometry and sequence duration against known content
Inspect a recognizable frame, including edges and color regions, and compare the imported result with the producer’s reference. Check the expected number of pictures and resulting duration under the chosen timing convention. Preserve any separate audio or metadata resources required for the real handoff.
If rows appear shifted, colors look wrong or frame boundaries drift, revisit the layout description before filtering the resulting image. Do not crop apparent padding from an incorrectly interpreted view and call it repaired source content. Retain the original bytes and known format description so a later recipient can reproduce the intended interpretation.
Worked example
A producer supplies packed RGB24 frames with an explicitly documented padded row stride. A receiver assumes tightly packed rows and sees shifted geometry. The next step verifies the actual layout and chooses a matching import, not a sharpening filter or a fabricated higher-resolution width. Timing is supplied separately before judging the sequence’s duration.
